I love browsing the site and everything is easy to find. There is just so much I get lost for hours. Sometimes I wish there were videos of some gems, but other than that I love shopping with GemSelect and I have referred the site to many people many times. I work in the jewelry industry myself and I love to show off what Ive had made with my gems from GemSelect! Thank you

I found what I was looking for...had to look up millimeters to inches. It would be nice to see something, like a quarter, in the pix to show relative size. I plan on buy loose gemstones for every month in the calendar

I like the site, it's easy to navigate. There are sometimes items I'm looking for that aren't there, but mostly I can find what I need.

Always find more niche sizes/shapes as my unconventional designs require from this website. Recommending to fellow designers in the creative atmosphere on the usual, specially due to the quality and certification of gems.
